Heat stress increases hepatic ferroportin levels in the livers of young and old rats. A: Liver samples from young (6 mo) and old (24 mo) rats were analyzed for Fpn protein expression in the nonheated condition, and at the indicated times after heat stress. Fpn expression was normalized to Ponceau staining, and ratios were further normalized to the young control. B: Fold induction of Fpn after heat stress in young and old rats at 0, 2 and 24 h after heating. Densitometry values from each heated time point were normalized to nonheated values within each age group. Results are expressed as means + SEM; n=7-9 young and old rats under nonheated conditions, and at each time point after heat stress. * Significant effect of aging; † significant effect of heat stress within an age group (p<0.05).
